Use the AMINES property method for amine systems with ranges of:
MEA DEA DIPA DGA
Temperature (°F) 90 – 280 90 – 275 90 – 260 90 – 280
Maximum H2S or CO2 Loading
(moles gas/mole amine)
0.5 0.8 0.75 0.5
Amine Concentration in
Solution(mass percent)
5 – 40 10 – 50 10 – 50 30 – 75
If the amine concentration is outside the recommended range, the Chao-
Seader method is used for K-values (only for that particular property
evaluation). |
